Two-Channel Insulated Driver Model ADUM3220 with Output Current of up to 4A ADuM3220ARZ is an insulated two-channel driver with an output current of 4 Amperes. It is based on iCoupler technology developed by Analog Devices Corporation. The driver combines a high-speed CMOS logic with monolithic transformers. It is much more effective than any alternative solutions, for instance, combinations of pulse transformers with buffer cells. ADuM3220 has two independent insulated channels. It differs from the drivers that coordinate high-level signals. ADuM3220 offers a real galvanic isolation between the input and each of the outputs. This allows transmitting the signal through a barrier insulant. The output of ADuM3220 has a through current protection. The driver also has a low level of active output signal. Both features are typical for power applications. The microcircuit works at input signal levels ranging from 3.0 to 5.5 Volts. Thus, it is compatible with low-voltage systems. The output stage works at voltages from 5 to 18 Volts. This is necessary for the synchronous AC/DC converters. The peculiarities of the driver include: peak-point output current: 4Amperes; high-precision time response; maximum signal propagation delay: 60 nanoseconds; maximum channel time mismatch: 5 nanoseconds; input logical levels: 3.3 to 5 Volts; switched voltage: 4.5 to 18 Volts; temperature protection operating level: +150 degrees Celsius output protection; low level of active output signal ...
